That is called Permanent Residency or green card. Generally, PR should stay in US for more than 183 days to keep their statues. While, a lot of grant, funding, projects and positions require US citizenship especially after 9/11. Professor in University is fine, Senior engineer of a company is also OK bahh.

再弱弱的问一问cerium:

一:中国是不承认双重国籍的.拿了绿卡就等于加入了美国国籍了吗?是不是就得称作"华人"了,那么拿了绿卡还不等于获得美国公民身份吗?

二:请你把"Professor in University is fine, Senior engineer of a company is also OK bahh."用汉语翻译一下.对于英文,我的理解有一些问题.我还没有弄明白,你是说在这两种情况下,"一边保留中国国籍,一边在美国的正常单位工作"是可以,还是不可以?

如果不介意的话,请用中文回答,非常感谢.

Got it.

拿了绿卡之后怎么才能算加入美国国籍?

是否可以在没有绿卡的情况下直接申请加入美国国籍?

你是替刘亦非问么?

cerium:
呵呵,你也看到了我在"大话影视"的发言呀.
不错,我确实是有感而发的.
中国的一些精英都外流了.
我深感遗憾,不平与愤怒.

请问:
居留五年, 要申请入籍.--------------------------我就是不申请,仍然保持绿卡,就是不加入,仍然保持中国国籍也可以吗?会遇到一些什么问题?会有人干涉吗?

It is ok to keep permanent resident statues without getting citizenship. The benefit for citizenship is
1. you can travel easily;
2. you are able to get involved into some company or project labeled citizen only, say, national defense.
3. Permanent resident will be easily deprived under crisis like 9/11, while citizenship won't.
